Ebay fee going insane, account was suspended.

Well i had a stealth account where i sold some counterfeit phones for half the market price.
Last buyer realized that was a fake phone after receiving a Samsung Galaxy S7 and made a chargeback, leaving my stealth paypal account in 400 negative. After that ebay banned the account Magiaris for security reasons and is still asking for fees which i wont pay for the sake of my butt, every month they are increasing the fee even if the account is suspended, october fee is 400 euro now by the face, and my last sale was in august. I dont sure how much they lied to me with fees, they think i own them 800 euro but i wont pay anything, also owning a negative balance of 400 to paypal.

Question is, why the hell do i need to pay seller fees after ban? Yeah they can take me to court, but i can manage without a lawyer only by telling the account was terminated and with it the fantasy debt they are trying to scam me with. Can they manage to send a stealth account with full fake datas to collection? I used a VIABUY IBAN to get the money from paypal, and only the bank account was in my name but the IBAN is dutch.
Last collector that knocked my door left with a purple eye. Normally collection agencies stop calling me after i insult them when they try to tell me something.

They will eventually sell your debt to a collection agency.

If you do not have your real details on the account, why worry?

IP adress, that is why i worry. I know they can't prove anything with an IP adress, but i have enough stress from Movistar collection agency claiming i own them even when i pay every month my bills. VPN and proxy using ebay is a bad idea, they somehow break your shield for some minutes and see you real IP.

Unless you attached ssn or real information (stealth info) they can't link you so you can just ignore and not pay.

they will not take you to court because of this .....

Thanks, that was all information i needed to know.
